Morisato Keiichi is an unlucky college guy. He has no luck scoring a date with the rich and popular Sayoko. He has bad luck in nearly everything he does. One evening while stuck at the male boarding house that he shares with his auto club senpais, he happens to make a call which gets connected to the heavens and to Belldandy. There, this goddess doesn't wait to announce she's coming for a personal visit, and she arrives via a mirror behind Keiichi. He is startled by her sudden appearance and doesn't believe she's real, nor that she can grant wishes. But he makes a wish -- for a girl like her to be by his side forever. His wish is granted and Belldandy is now contracted to stay with Keiichi on Earth for the rest of his life.

Sometime in the future, insects on Earth have become immune to insecticides. As such, small, uber-kawaii dolls have been created to take care of insect problems. Thus they battle insects with their vast array of weapons, and do other things as well.
